|
|
JVC TV has been working fine for almost 2 years. TIVO is attached. I was doing a search for some shows when I noticed that the Blue Sync seemed to be off. There was a double image in the lettering that was blue.
While searching, all of the sudden the screen went black and I heard a heartbeat kind of thumping coming from the speakers. The TV did not respond to the remote or the manual power button. Blue power light stayed lit.
I unplugged the TV and then plugged it back in after a minute or so. Heard the thumping again and then the blue power light started blinking on and off. No other response.
That was quite a while ago... Now I got some info that said the problem was a condition called power supply overcurrent shutdown. The TV is going into a protection mode to prevent further circuit damage.
Now, the TV sat at a repair shop for a while and then I was told it was going to take $400 to fix the problem.
I can't afford it so I am hoping that the issue is something I can fix myself. I am relatively intelligent, can read a schematic and am handy with electronics and tools.
Can this be something I can fix at home??
Thanx for any info...

Thanx for the reply.. Can you tell me what the HOT and the VM Board FET is?? I can find them on the circuit diagrams I have. I just need to know where to look.
Thanx
